[OTHER OPTIONS]
There are some options to discuss with Garchomp. Stone Edge, Brick Break, and Crunch are other attacks Garchomp could make use of. Unfortunately, they all have very situational uses and are generally repetitive alongside its STAB attacks. Dual Chop could replace Dragon Claw on almost any set, sacrificing 10% accuracy for the ability to potentially hit through Substitutes. Early DPP saw the birth of mixed Garchomp, and Draco Meteor or Surf combined with some Special Attack EVs could still be used as a gimmick to take down enemies like Hippowdon and Gliscor.</p>
<P>Toxic is a status move Garchomp has, and could work (even on the Choice sets) to debilitate bulky Water- or Ground-types that try to check Garchomp. Substitute can be used to try and fully abuse Garchomp's Sand Veil. Unfortunately, a much faster metagame, a ban on Bright Powder and Lax Incense, and the overwhelming popularity of Politoed and Ninetales make Sand Veil abuse much more difficult in BW. Also, a defensive set with RestTalk could be used for reliable recovery, as well as that fast Dragon Tail. Unfortunately, Rough Skin is illegal with Sleep Talk.
